HERMANN SUSS, OF MARBURG, PRUSSIA, GERMANY.

MAGNESIUM-LAMP.

SPECIFICATION forming part of Letters Patent N 0. 370,904, dated October 4, 1887.

Application filed July 30,1886.

To all whom it may concern:

Be it known that I, HERMANN Siiss, of Marburg, on the Lahn, Prussia, Germany, have invented a new and Improved Magnesium-Lamp, of which the following specification is a full, clear, and exact description.

The invention relates to the construction of a magnesium-lamp having a constant luminous effect.

The hithertoconstructed magnesium-lamps had the great inconvenience that the flames burned very irregularly, and that the lighting power fluctuated considerably. This inconvenience resulted partially from the large quantities of residues of combustion, which are deposited on the combustion place, and thus prevent the wire from advancing in a regular manner, or from the ashes produced by the combustion being not stripped away, but adhering for some time to the metallic band, and thus cause by their weight an accelerated advancement of the wires. The hereindescribed construction has for its purpose to remedy these inconveniencesl The invention consists of the various features of improvement hereinafter more fully described.

In the accompanying drawings, Figure 1 is a side view of the lamp. Fig. 2 is a top view, and Fig. 3 is a front view, of the same. Figs. 4., 5, and 6 are details, on an enlarged scale, referred to in the specification.

The magnesium band is wound on a bobbin, a, in one or more strips close to each other, and conducted between two pairs of rollers, b c and d f, which are put in motion by means of a clock-work, G. The band is regularly moved forward by these rollers, and passes them over a holder, h, on the outer edge of which it is burned. This holder is provided with a casing, i, which surrounds the holder, and capable of being moved backward and forward. During this to-and-fro motion the forward edge of the case passes over the forward edge of the holder h and into the plate It, supporting the reflector of the lamp. This plate It is perforated, and surrounds both the holder h and easing t, being set back from the forward edge of the holder, as shown. The

Serial No. 209.600. (No model.)

deposit produced by thevcombustion is thus removed from the holder and the case at the same time. This forward-aud-backward motion is produced by the clockwork by means of the levers Z, m, n, and 0. The ashes formed by the combustion do not detach themselves immediately from the metal, but adhere sufficiently, so that they hang down as fillets, which pass between the rollers 19 q 1', put in motion by the clock-work, and rotating in the direction indicated by the arrows, (see Fig. 1,) and arrive at the cutting device .9 t, where they are cut into small pieces, which fall down one after another. The above-mentioned inconveniencethat the ashes by their weight cause an accelerated advancement of the magnesium band, and consequently an accelerated consumption--is entirely removed.

The two arms 8 and t of the cutting device are provided with cutters s t, respectively, which in cutting off the fillet come in contact with each other only for a moment. A stagnation or a tearing off of the fillets is thus prevented.

The cutting device is moved by means of the clock-work G in the following manner: On a rotating shaft, u, is a curved disk, 1). Upon this disk slides a roller, 10, which is fixed to one end of a bent lever, w y. On the other end of this lever is pivoted a rod, 2, which is attached to a crank, A, fixed with the arm 8 of the cutting device on the same axle A. The other arm, t, of the cutting device is attached to a shaft, A, provided with a wheel, 1), which meshes with a wheel, 1), fast on the shaft A. The roller w is pressed, by means of a spiral spring, B, attached to the bent lever to y, against the disk 2:. As the recesses in the disk 1) are arcs which have the same radius as the roller 10, the reciprocal position of the cutting device is continuously changed, and the cutting-edges of the arms 8 and t touch each other only for amoment.

Having now fully described the nature of this invention and in what manner the same is to be constructed and used, I declare that what I claim is 1. The combination of bobbin a and clock work G with holder h and easing i, which sur rounds snid holder and is connected to the crate said cutter, substantially as and for the 10 clock-work G by a train of levers, and with purpose specified. perforated plutek, surrounding both the holder In testimony whereof I have signed my name h and easing i, and set back from the forward to this specification in the presence of two subedge of the holder, substantially as specified. scribing witnesses.

2. The combination of bobbin a, holder 71, and casing 1 surrounding the same, with the l Witnesses: rollers 12 q r and cutters s t, and with the 08.111 0. \VICHMANN, u, roller 10, bent lever x y, and arms 8 t to 0p- B. 1:101.
